Not every decision is given out on appeal.
For example, if a player is bowled he's out.
I say this because I think it's time the umpires take these sorts of things out of the players hands and review the decision without the filers having to appeal.
This takes away the "sportsmanship behaviour" out of it and if it's out then it's out.
No ambiguity
You want to seriously remove the appeal from cricket?
How do umpires know which decisions to review? Or do we wait to review every ball?
How is there "a decision" without a question being put?
